How We Researched These Picks

We did not physically cut lumber with these six saws ourselves. Instead, we built this guide from manufacturer spec sheets for blade size, cut depth, and no-load speed; from professional test data published by outlets like Pro Tool Reviews and Tool Box Buzz; and from recurring patterns in verified owner feedback on retailer listings at Home Depot, Lowe’s, and Amazon, which tend to surface the long-term issues — a shoe that bends, a guard that sticks, a battery connection that wears — that a spec sheet never mentions.

Where a number appears in this guide, we’ve named its source in the same sentence. For more on how we vet products before they’re featured, see our editorial standards page.

We also narrowed a crowded category to six saws on purpose. Dozens of 18V/20V circular saws are currently on the market, but most home DIYers are better served by matching one clear scenario — budget, existing battery platform, first-time purchase — to one well-reviewed saw than by scrolling a longer list that doesn’t map to anything specific. Prices are approximate, current as of publication, and change frequently — confirm the latest price with the retailer before buying.

Which Cordless Circular Saw Cuts Through the Thickest Lumber?

The Milwaukee M18 FUEL 7-1/4″ Circular Saw (2834-20) posts the deepest 45-degree bevel cut and the highest no-load speed of any saw in this roundup: 2-5/8 inches at 90 degrees, 2-1/16 inches at 45 degrees, and 6,000 RPM, according to Pro Tool Reviews’ published test data. Pro Tool Reviews scored it 9.7 out of 10, calling out “improved cutting power” and a saw that cut through three layers of material in a single pass without slowing down.

Pricing runs $249 for the bare tool, with a kit that bundles a 12.0Ah battery, charger, and tote running $449, per that same review.

• Best for: engineered lumber, doubled-up framing members, deck ledger boards, and anyone who wants the shortest path from “cut” to “done.”
• Must-have: the extra cut depth at 45 degrees, which is exactly where thinner saws run out of blade on beveled deck and fence cuts.
• Nice-to-have: the 12.0Ah battery in the top kit, which is more capacity than most DIYers need for occasional projects.
• Dealbreaker: this is the most expensive bare tool in the roundup, and Pro Tool Reviews found “no significant drawbacks” in testing — but that performance carries a price premium over every other saw here.

Owner feedback we reviewed on retailer listings echoes the professional consensus: buyers moving up from smaller saws consistently describe the depth and bevel detents as more precise than what they replaced, rather than flagging any recurring failure point. That’s an unusually clean verdict for a tool this powerful.

Do You Need a Corded or Cordless Saw for Framing and Deck Work?

For the overwhelming majority of DIY framing, decking, and sheet-goods work, a modern 18V/20V brushless cordless saw is genuinely enough. The saws in this roundup match or approach corded cut depth in 2x lumber and plywood, and none of them require you to run an extension cord across a yard or up a ladder.

Where a corded saw still earns its keep is all-day, every-day professional framing, where continuous runtime matters more than battery swaps, and in wet-rated or pressure-treated lumber cutting done for hours at a stretch. For a weekend deck, a shed, or trim and sheet-goods projects, the trade-off tips clearly toward cordless: no cord to manage, and a battery you likely already own if you’ve bought a drill or impact driver on the same platform.

Which Saw Makes Sense If You Already Own DeWalt 20V MAX Batteries?

If you already own a 20V MAX battery and charger — say, from our previously reviewed DeWalt 20V Max Cordless Drill — the DeWalt XR 7-1/4″ Circular Saw (DCS570B) lets you add a saw without starting a second battery platform. It’s rated for a 2-9/16-inch cut at 90 degrees, a 57-degree max bevel, and 5,200 RPM no-load, per Pro Tool Reviews’ spec breakdown, and weighs 8.16 pounds bare.

Pro Tool Reviews scored it 8.1 out of 10 and described it as “a legitimate corded sidewinder replacement,” while noting that DeWalt’s own FlexVolt line and Makita’s rear-handle saws deliver more raw power for buyers who need it. Tool-only pricing sits at $159, with the DCS570P1 kit — a 5.0Ah battery, charger, and bag — at $399, per that same review.

• Best for: existing DeWalt 20V MAX owners adding a saw to a drill or driver they already run.
• Must-have: shared batteries and chargers across DeWalt’s drill, driver, and outdoor tool lineup.
• Nice-to-have: the 57-degree max bevel, which exceeds the 45-50 degrees most saws here top out at.
• Dealbreaker: Pro Tool Reviews specifically flagged the missing rafter hook, a small omission that matters more than it sounds like on a jobsite or roof.

Which Cordless Saw Feels Closest to Running a Corded Saw?

The Makita 18V X2 LXT (36V) 7-1/4″ Circular Saw (XSH06Z) runs two 18V batteries in tandem to reach 36V, and the extra voltage shows up in the cut: a 2-5/8-inch depth at 90 degrees and a 0-6,000 RPM range, per Tool Craze’s published review. That review called performance “top notch for cordless” and said it rivals corded saws, while praising the magnesium shoe and housing, dual battery fuel gauges, and onboard blade-wrench storage.

The bare tool lists for $199, with the XSH06PT kit — two batteries and a charger — at $349, per that same source. The same review also found real-world runtime came up short of Makita’s claims, measuring 364 cuts in testing against a 610-cut manufacturer figure, and flagged a lower blade guard that occasionally sticks and a secondary handle several testers found too small.

• Best for: buyers who want the least compromise between cordless convenience and corded-saw cutting feel.
• Must-have: the dual battery fuel gauges, which tell you exactly how much runtime is left on each pack before a big cut.
• Nice-to-have: a rafter hook, which Makita sells separately rather than including.
• Dealbreaker: it needs two 18V batteries loaded at once, and at 10.5 pounds with batteries installed, per Tool Craze, it’s the heaviest saw in this roundup by a meaningful margin.

What’s the Best Budget Cordless Circular Saw Right Now?

The Ryobi ONE+ HP 18V Brushless 7-1/4″ Circular Saw (PBLCS300B) is rated for a 2-7/16-inch cut at 90 degrees and a 1-13/16-inch cut at 45 degrees, with a no-load speed of 4,300 RPM on Ryobi’s HIGH PERFORMANCE battery (3,700 RPM on a standard ONE+ pack), according to Tool Box Buzz’s published test data. That same review credited the brushless motor with “up to 40% faster cutting” than Ryobi’s prior brushed model and praised the right-blade layout for line-of-sight, plus an electric brake that stops the blade in under two seconds.

The bare tool carries a $129 MSRP per Tool Box Buzz, and Home Depot’s listing for the PBLCS300K1 kit — which bundles a 4.0Ah HIGH PERFORMANCE battery and charger — has repeatedly priced at or below that bare-tool figure during promotions. That’s an unusual reversal in this category, where kits normally cost meaningfully more than the tool alone.

• Best for: occasional DIYers and first-time toolbox builders who don’t want to pay a professional-grade premium.
• Must-have: the HIGH PERFORMANCE battery pairing, which Tool Box Buzz found meaningfully improves cutting speed over a standard ONE+ pack.
• Nice-to-have: the dual sightline dust blower, which keeps the cut line visible without a shop vac running.
• Dealbreaker: the stamped steel shoe is more prone to bending than the cast aluminum or magnesium shoes on the pricier saws above, and the LED work light is partially blocked by the bevel adjustment hardware, per Tool Box Buzz.

What’s the Easiest Saw for a First-Time Cordless Buyer?

The Skil PWRCore 20 Brushless 6-1/2″ Circular Saw (CR6413) is the lightest saw in this roundup at 5.2 pounds bare and 6.0 pounds with its battery installed, per Pro Tool Reviews’ published specs, with a 2-1/4-inch cut at 90 degrees, a 1-5/8-inch cut at 45 degrees, and 5,500 RPM no-load. Pro Tool Reviews scored it 8.7 out of 10, describing “confident cutting power” for a compact saw and praising a Shadow Line LED with a built-in cleaning dial for visibility.

It’s sold as a $129 kit that includes a 2.0Ah battery and charger, with no separate bare-tool listing for this brushless model, per that same review. That review also noted the trade-offs that come with the lighter price and weight: construction that’s less durable than premium professional saws, and the absence of positive depth and bevel detents found on pricier models.

• Best for: a first cordless saw for someone who hasn’t bought into any battery platform yet, plus anyone prioritizing low weight for overhead or one-handed cuts.
• Must-have: the sub-6-pound total weight, which matters most on repetitive cuts or extended overhead work.
• Nice-to-have: the Shadow Line LED, genuinely useful but not essential if you’re working in good light.
• Dealbreaker: the 6-1/2-inch blade tops out at a shallower cut than the 7-1/4-inch saws above, so doubled-up framing lumber can be tighter to clear in a single pass.

Is There a Genuinely Cheap Option for Building a Tool Kit From Scratch?

The Craftsman V20 6-1/2″ Cordless Circular Saw is the lowest-priced saw in this roundup at either purchase path: the bare tool (CMCS500B) lists for $99, and the CMCS500M1 kit — a 4.0Ah battery and charger included — lists for $199, per Acme Tools’ current listings. It’s rated for 4,000 RPM and a bevel that adjusts to 50 degrees, per Craftsman’s own product page, and includes an 18-tooth blade in the box.

If you’re outfitting a first tool kit alongside our Beginner’s Home Tool Kit essentials, Craftsman’s V20 platform also covers drills, drivers, and yard tools on the same battery, which matters if this is the first cordless purchase in the house rather than an addition to an existing one.

• Best for: a genuinely tight budget, or a first cordless tool purchase with no existing battery platform to build around.
• Must-have: the lowest all-in kit price of any saw here, at $199 for saw, battery, and charger.
• Nice-to-have: the 50-degree bevel range, competitive with saws costing well more.
• Dealbreaker: this is a brushed motor, not brushless, which means more heat buildup and shorter long-term motor life than every other saw in this guide, and Craftsman’s V20 line has a noticeably thinner professional-reviewer footprint than Milwaukee, DeWalt, Makita, or Ryobi, so long-term reliability data here is thinner too.

6-1/2″ or 7-1/4″ Blade: Which Cordless Circular Saw Size Do You Actually Need?

A 7-1/4-inch blade is the standard size for framing lumber, and it’s what gives the Milwaukee, DeWalt, Makita, and Ryobi saws above their deeper cut capacity — enough to clear a 2x board in a single pass at both 90 and 45 degrees. A 6-1/2-inch blade, like the ones on the Skil and Craftsman saws, is lighter, cheaper, and plenty capable for plywood, OSB sheet goods, fencing, and single-pass 2x cuts at 90 degrees, but it loses more margin once you bevel the cut or double up material.

The practical rule: if your projects are mostly sheet goods, fencing, and light framing, a 6-1/2-inch cordless circular saw saves weight and money without costing you real capability. If you’re regularly framing, decking, or beveling thicker stock, the extra half-inch to three-quarter-inch of blade on a 7-1/4-inch saw buys real headroom.

How Much Do You Actually Save by Staying on Your Current Battery Platform?

Every saw above is sold two ways: as a bare tool for people who already own batteries on that platform, and as a kit for people starting from zero. The gap between those two prices is really the price of the battery and charger — and it varies more by brand than most buyers expect. We built the table below ourselves from the bare-tool and kit prices cited throughout this guide, subtracting one from the other to isolate what each platform’s battery and charger actually cost.

Saw	Bare-tool price	Kit price (battery + charger)	Implied battery/charger cost
DeWalt XR DCS570B	$159	$399 (DCS570P1)	$240
Milwaukee M18 FUEL 2834-20	$249	$449 (12.0Ah + tote)	$200
Makita X2 LXT XSH06Z	$199	$349 (XSH06PT)	$150
Craftsman V20 CMCS500B	$99	$199 (CMCS500M1)	$100
Ryobi ONE+ HP PBLCS300B	$129	~$99–$130 (PBLCS300K1, promo-dependent)	~$0–$30 (outlier)
Skil PWRCore 20 CR6413	Not sold bare	$129 (kit only)	Not applicable

This is our own analysis, built from the retailer and reviewer prices cited above rather than a manufacturer claim, and retail prices shift with sales, so treat the dollar figures as directional rather than exact. Two things stand out. First, DeWalt’s implied battery-and-charger cost is the highest of the group at $240, which means joining the DeWalt platform cold costs more than it does with any other brand here — but it also means an existing DeWalt owner saves the most in relative terms by buying the DCS570B bare instead of a rival’s kit. Second, Ryobi is the outlier: its 4.0Ah kit has repeatedly priced at or near the bare-tool cost per Home Depot’s listing, so there’s little financial reason to buy the Ryobi saw tool-only even if you already own ONE+ batteries.

The practical takeaway: if you already own two or three batteries and a charger on a given platform, price every future cordless tool at its bare-tool cost, not its kit cost, because that’s the number that actually applies to you. If you’re starting from nothing, compare kit to kit — a $159 bare-tool price looks cheap right up until you also need to buy a $240 battery and charger to run it.

How Do You Use a Cordless Circular Saw Safely?

Every saw in this roundup is a mainstream, brushless (or in Craftsman’s case, brushed) major-brand tool with standard safety features like blade guards and electric brakes, and we’re not making any claim that one of these six is safer than another. Safe use comes down to following the manufacturer’s instructions in each saw’s manual, not the brand on the shoe.

That means always wearing eye protection, letting the lower blade guard retract on its own rather than wedging it open, keeping hands clear of the blade path and cut line, supporting both sides of the material so the kerf doesn’t pinch the blade, and unplugging or removing the battery before changing a blade or adjusting depth and bevel settings. Follow the blade manufacturer’s guidance on matching blade type to material, and never remove or disable a guard to “see the cut line” better — use the sightline notch or LED the saw already has instead.

What Else Actually Matters When You’re Shopping for One?

Battery platform is the decision that outlasts any single saw. Once you own a battery and charger in a brand’s ecosystem, every future cordless tool in that lineup gets cheaper, because you’re only ever paying the bare-tool price — which is exactly the logic behind the cost matrix above. It’s worth deciding your platform before you decide your saw.

Brushless motors, used in five of the six saws here, matter less as a marketing term and more for what they mean in practice: less heat, no brushes to wear out, and typically better runtime per charge than an older brushed design like Craftsman’s. Weight matters more than most buyers expect walking in — a saw that’s two pounds lighter is the difference between finishing a long rip in one pass and stopping to reposition.

If fastening rather than cutting is your next purchase, our cordless impact driver roundup matches five drivers to specific jobs the same way this guide matches saws. And if you’re assembling a first kit rather than adding to an existing one, start with our Beginner’s Home Tool Kit guide before you commit to a battery platform.

Frequently Asked Questions

How long does a cordless circular saw run on one battery charge?

Runtime depends far more on battery amp-hours and cut type than on the saw itself, which is why manufacturer cuts-per-charge claims vary so widely and don’t always hold up in independent testing — Tool Craze, for instance, measured 364 cuts on the Makita XSH06Z against a 610-cut manufacturer figure. A larger-capacity battery (4.0Ah or higher) will outlast a 2.0Ah pack on the same saw by a wide margin.

Will a cordless circular saw bog down on thick or pressure-treated lumber?

Modern brushless 18V/20V saws handle standard 2x pressure-treated lumber without issue, but denser or wetter stock draws more current and drains a battery faster. A sharp, appropriately-toothed blade matters as much as the saw’s rated power for avoiding bogging down.

Do all these saws use the same battery, or are the platforms locked to one brand?

Each brand’s batteries are locked to its own platform: Milwaukee’s M18, DeWalt’s 20V MAX, Makita’s 18V LXT, Ryobi’s ONE+, Skil’s PWRCore 20, and Craftsman’s V20 are not interchangeable with one another. That’s exactly why the battery-platform cost matrix above matters before you buy.

Is a brushless motor worth paying extra for?

For most buyers, yes. Brushless motors run cooler, have no brushes to wear out, and generally deliver more runtime per charge than brushed designs like the one in Craftsman’s V20 saw. The trade-off is usually a higher price, which is why the brushed Craftsman remains the cheapest saw in this roundup.

What safety gear do you need beyond what comes in the box?

At minimum, safety glasses or a full face shield, hearing protection for extended cutting sessions, and a stable way to clamp or support your material so the cut doesn’t pinch the blade. Always follow the safety guidance in the specific saw’s manual, since guard design and warnings vary by model.

How much should you budget for a first cordless circular saw, all in?

Budget $99 to $199 for a genuinely capable kit with a battery and charger included if this is your first cordless tool, based on the Craftsman and Skil pricing cited in this guide, or $349 to $449 if you want the top-tier power of the Makita or Milwaukee picks. If you already own batteries on a platform, subtract the bare-tool price instead using the cost matrix above.
